Having a hard time distinguishing between what happened and what you think should have happened.

Not realizing that surly people are probably going through something terrible in their life.

The inability to communicate your ideas because you wrongly assume others have the necessary background to understand what you’re talking about.

Assuming history is a guide to the future, when in reality, “things that have never happened before happen all the time,” as Scott Sagan says.

Exaggerating the importance and influence of your social group.

Incorrectly assuming the views of one person reflect those of a broader group that person associates with.
